本发明一般涉及通过有线电视基础设施提供交互式电视服务，尤其涉及在视频点播(video-on-demand)平台上管理、转换和显示视频内容的系统和方法，特别是在电视机上用于下查式(drill-down)导航的广告显示以及消费者生成的分类广告的显示。The present invention relates generally to the provision of interactive television services over a cable television infrastructure, and more particularly to systems and methods for managing, converting, and displaying video content on a video-on-demand platform, particularly for viewing on a television set. Ad display for drill-down navigation and display of consumer-generated classified ads.

背景技术Background technique

在美国和其它技术先进国家，有线电视(CATV)系统被用于将电视服务传递到观看电视的千家万户。典型的CATV系统具有电缆服务提供商头端，该头端装备有视频服务器从而通过分布线路将CATV节目信号发送到各地方的节点并且从那里再发送到TV订户的家。在订户家里，CATV节目信号被发送到一个或多个客户-房屋TV，这些TV耦合到用于信道调谐的外部机顶盒或者装备有内部有线频道调谐器。In the United States and other technologically advanced countries, cable television (CATV) systems are used to deliver television service to millions of households that watch television. A typical CATV system has a cable service provider headend equipped with video servers to transmit CATV program signals over distribution lines to various local nodes and from there to TV subscribers' homes. At the subscriber's home, the CATV program signal is sent to one or more customer-premise TVs coupled to external set-top boxes for channel tuning or equipped with internal cable channel tuners.

当前的CATV机项盒提供了在订户和CATV头端之间进行信道切换和节目访问的各种功能。更先进的数字机顶盒可以单独地从CATV头端中寻址，并且也允许订户通过遥控单元输入他们的选择输入，以便在连接到CATV头端的电缆的后通道上进行传输，由此能够使订户访问到交互式电视服务和其它类型的先进数字TV服务。交互式电视系统的主要类型通常被称为“视频点播(VOD)系统，其中观看者可以通过遥控单元向机顶盒输入视频节目的选择并使所期望的视频节目瞬时传递过来以便显示在电视机上。这种VOD应用可以包括电影、纪录片、历史上的体育事件、电视节目、通知、广告、音乐视频、短片以及信息的单屏显示。基于VOD的交互式电视服务一般允许观看者使用遥控器在屏幕上的菜单中移动光标，并从所存储的视频节目的各种标题中选择想要观看的节目。先进的遥控单元包括带VCR相似功能的按钮控制，能够使观看者开始、停止、暂停、后退、或重播所选的视频节目或片段。将来，基于VOD的交互式电视服务可以与其它先进的交互式电视服务(比如网页浏览、电子邮件、电视购物(“t-商务”)交易、以及多媒体传递)结合在一起或一起传递，。Current CATV set-top boxes provide various functions for channel switching and program access between subscribers and CATV head-ends. More advanced digital set-top boxes are individually addressable from the CATV headend, and also allow subscribers to input their selections via the remote control unit for transmission on the rear channel of the cable connected to the CATV headend, thereby enabling subscribers to access to interactive television services and other types of advanced digital TV services. The main type of interactive television system is often referred to as a "Video on Demand (VOD) system, in which the viewer enters a selection of video programs into a set-top box via a remote control unit and has the desired video program delivered instantaneously for display on the television. This A VOD application can include single-screen displays of movies, documentaries, historical sports events, TV shows, announcements, advertisements, music videos, short films, and information.VOD-based interactive television services generally allow viewers to Move the cursor in the menu and select the program you want to watch from various titles of stored video programs.Advanced remote control units include button controls with VCR-like functions, which enable viewers to start, stop, pause, rewind, or Replay selected video programs or segments. In the future, VOD-based interactive television services may be integrated with other advanced interactive television services (such as web browsing, e-mail, TV shopping ("t-commerce") transactions, and multimedia delivery) combined or delivered together,.

随着交互式电视服务的交互式功能和客户覆盖区域不断增大，广告商和内容提供商发现使用点播式广告、节目内容和TV交易对于家庭观看者越来越有吸引力。正在设计VOD内容传递平台，为无缝地且方便地将类型广泛的点播式广告、内容和交易服务传递到家庭观看者。一种先进VOD传递平台的示例是马萨诸塞州Needham镇的Navic Systems公司(d/b/a Navic Networks)所提供的N-波段(TM)系统。这是一种集成系统，它为第三方应用程序开发者提供了应用程序开发平台，用于开发新的VOD服务应用程序、观看者界面和辅助交互式服务，以便部署在全美国的电缆服务区域中CATV操作人员的VOD信道上。在2002年5月30日提交的美国专利申请2002/066,106中包含了关于Navic N-波段系统的详细描述，该专利被引用在此作为参考。As interactive features and customer coverage of interactive television services continue to expand, advertisers and content providers are finding the use of on-demand advertising, programming content and TV deals increasingly attractive to home viewers. The VOD content delivery platform is being designed to seamlessly and conveniently deliver a broad range of on-demand advertising, content and transactional services to home viewers. An example of an advanced VOD delivery platform is the N-Band(TM) system offered by Navic Systems, Inc. (d/b/a Navic Networks) of Needham, MA. An integrated system that provides an application development platform for third-party application developers to develop new VOD service applications, viewer interfaces and ancillary interactive services for deployment in cable service areas throughout the United States On the VOD channel of CATV operators in China. A detailed description of the Navic N-band system is contained in US Patent Application 2002/066,106, filed May 30, 2002, which is incorporated herein by reference.

先进的数字机顶盒还有收集数据的能力，比如观看者所调谐的信道和所观看的节目的记录。机顶盒可以被设计成自动地收集该数据并将该数据报告给电缆头端。在头端位置处，可以集中许多用户的观看者数据(其中已除去个人标识数据)，并且被提供给广告商和节目赞助商以便针对用户偏好设计并定位新广告和节目的信息，由此增大观众数目，使每一个广告或节目给观看者留下更强烈的印象，并最终增加收入。Advanced digital set-top boxes also have the ability to collect data, such as a record of the channels the viewer tunes to and the programs they watch. The set-top box can be designed to automatically collect and report this data to the cable headend. At the head-end location, viewer data (with personally identifying data removed) for many users can be aggregated and provided to advertisers and program sponsors to design and target new advertisements and programs to user preferences, thereby increasing The large number of viewers makes each advertisement or program leave a stronger impression on viewers and ultimately increase revenue.

目前所提供的VOD广告和节目一般都是针对大众而制作的。令人特别期待的是采用一种VOD传递平台来传递广告、促销宣传、节目以及信息内容，允许观看者容易且可视化地巡航到感兴趣的特定项目这种用于内容传递的可视化导航将会更可能产生一种令观看者满意的经历，并使各观看者参与点播式电视服务和交易。再令人特别期待的是采用一种VOD传递平台来接收来自个人的用户广告的上传，诸如通过联机网络，以便供电视订户搜索、巡航和显示。VOD advertisements and programs currently offered are generally made for the public. It is particularly expected to adopt a VOD delivery platform to deliver advertisements, promotions, programs and information content, allowing viewers to easily and visually navigate to specific items of interest. This visual navigation for content delivery will be more It is possible to create a satisfying viewer experience and engage each viewer with on-demand television services and transactions. Still more particularly desirable is the use of a VOD delivery platform to receive uploads of user advertisements from individuals, such as over online networks, for search, navigation and display by television subscribers.

发明内容Contents of the invention

根据本发明的第一目的，用于传递模板化VOD内容的视频点播(VOD)内容传递系统包括：According to a first object of the present invention, a video-on-demand (VOD) content delivery system for delivering templated VOD content comprises:

(a)位于电缆头端处的VOD应用程序服务器，它管理着多个模板的数据库，以便响应于从观看者的电视设备发送到电缆头端的观看者请求信号所请求的特定视频内容单元而产生模板化的VOD内容；(a) a VOD application server at the cable headend that manages a database of templates to generate in response to specific units of video content requested by viewer request signals sent from the viewer's television equipment to the cable headend templated VOD content;

(b)视频服务器，用于存储被编码成视频内容单元的视频内容，还用于响应于VOD应用程序服务器而提供所请求的视频内容单元以便传递到观看者的电视设备；以及(b) a video server for storing video content encoded into units of video content and also for providing requested units of video content for delivery to the viewer's television equipment in response to the VOD application server; and

(c)应用程序数据中心，用于创建并存储多个不同的模板，这些模板按一个层次排序，以便展示按分级次序归类的不同选择类型的视频内容单元，其中用于显示层次级别较高的视频内容单元的模板包括到层次级别较低的一个或多个模板的链接，所述多个分级排序的模板和链接被存储在VOD应用程序服务器所管理的数据库中，以及(c) an application data center for creating and storing a plurality of different templates sorted by a hierarchy for displaying different selected types of video content units in hierarchical order, wherein the display hierarchy is higher The templates of the video content unit include links to one or more templates with lower hierarchical levels, the plurality of hierarchically ordered templates and links are stored in a database managed by the VOD application server, and

其中所述VOD应用程序服务器响应于所选的层次级别较高的视频内容单元的观看者请求，从所述数据库中检索相应的模板并从所述视频服务器中检索相应的视频内容单元，从而在观看者的电视设备上提供模板化的VOD内容显示，该显示包括到层次级别较低的视频内容单元的一个或多个链接，并且当观看者请求选择模板化VOD内容中所显示的到层次级别较低的视频内容单元的链接时，检索相应的层次级别较低的模板和视频内容单元，以便显示在观看者的电视设备上，由此能够使用户在模板化VOD内容的电视显示中使用下查式导航。Wherein, the VOD application server retrieves the corresponding template from the database and retrieves the corresponding video content unit from the video server in response to the viewer's request of the selected higher-level video content unit, so that A templated VOD content display is provided on the viewer's television device, the display includes one or more links to video content units at lower levels of the hierarchy, and when the viewer requests to select the displayed to hierarchy level in the templated VOD content When linking to a lower video content unit, the corresponding lower-level template and video content unit are retrieved for display on the viewer's TV device, thereby enabling the user to use the lower Check-style navigation.

在模板化VOD内容传递系统的较佳实施例中，该系统使用了模板化的内容传递来创建用户界面，以便用户在越来越多并行链接的更特定模板(显示广告)类型中巡航以达到用户感兴趣的目的主题。这里称之为“下查式广告”，一系列越来越多的更特定显示广告类型允许订户巡航到感兴趣的目的主题，，同时通过反映到感兴趣的目的主题的观看者路径的一系列广告的移动而具有独特的视觉体验。In a preferred embodiment of the templated VOD content delivery system, the system uses templated content delivery to create a user interface so that the user navigates through more and more parallel linked more specific template (display advertisement) types to achieve The purpose topics that the user is interested in. Here referred to as “Drilldown Ads,” a series of increasingly more specific display ad types that allow subscribers to navigate to destination topics of interest while passing through a series of Ads move with a unique visual experience.

作为涉及汽车广告的一个示例，用户界面可以提供分级排序的视频显示广告，这些广告以汽车制造商的广告作为开始，显示时还带有多种型号的广告链接。观看者可以使用遥控单元选择特定型号的广告，显示时也带有更多特定级别的广告链接，比如“顾客包装”、“特色/选项”、或“颜色/风格”等，直到它到达订户感兴趣的目的主题为止。观看者由此能够巡航到感兴趣的特定内容，同时还能够浏览汽车制造商、型号、型号A、特色等的视频广告显示。相似的是，观看者可以在浏览过当地经销商、经销商A、目前的促销宣传等的视频广告显示的同时，巡航到感兴趣的特定内容。模板化的VOD广告是应用户的每一个当前请求搜索VOD应用程序数据库而动态生成的。这能够使系统动态地生成并显示更新的仍属当前的广告内容。例如，如果汽车制造商改变了可购买的型号类型，或如果当地经销商A改变其当前的促销宣传，则可以用系统数据库上的新内容和选择选项来更新广告商的广告，并且可以动态地生成新的模板化广告，从而有线电视公司不再需要为新广告进行拍摄、制作、签合同和安装。使用这种下查式导航方法，便可以启用许多其它类型的广告、主题以及其它交互式电视应用。通过下查导航，也可以跟踪、仿形和/或确定观看者导航路径所呈现出的选择或偏好作为反馈数据，以便广告商细微调节下查式广告的设计。As an example involving automotive advertising, a user interface could provide a hierarchical video display of ads that begin with an ad for the car manufacturer and display links to adverts for various models. The viewer can use the remote control unit to select the ad for a specific model, which is also displayed with links to more specific levels of ad, such as "Customer Packaging", "Features/Options", or "Color/Style", etc., until it reaches the subscriber's perception subject of interest so far. Viewers are thus able to navigate to specific content of interest while also browsing video ad displays for car makes, models, Model A's, specialties, and the like. Similarly, a viewer can navigate to specific content of interest while browsing through video ad displays for a local dealer, dealer A, current promotions, etc. Templated VOD advertisements are dynamically generated by searching the VOD application database at each current request of the user. This enables the system to dynamically generate and display updated, still current ad content. For example, if a car manufacturer changes the types of models available for purchase, or if local dealer A changes its current promotion, the advertiser's ad can be updated with new content and selection options on the system database, and can be dynamically Generate new templated ads, eliminating the need for cable companies to film, produce, contract and install new ads. Using this method of drill-down navigation, many other types of advertisements, themes, and other interactive television applications can be enabled. Drilldown navigation can also track, profile and/or determine the choices or preferences presented by the viewer's navigation path as feedback data for advertisers to fine-tune the design of the drilldown ad.

具体实施方式Detailed ways

参照图lA，用于VOD内容传递系统的整个系统体系结构包括位于电缆头端处的VOD应用程序服务器10。VOD应用程序服务器10管理着模板和视频内容段的数据库11，视频内容段来自用于生成模板化的VOD内容的视频服务器12。VOD内容是响应于观看者请求信号而生成的，该请求信号是从观看者的电视设备的数字机顶盒21中经数字电缆电视系统13而发送到位于电缆头端处的VOD应用程序服务器10的。VOD应用程序服务器10的类型可以是能够装入该服务器并运行于该服务器上的任何符合兼容性而开发的VOD应用程序。这种VOD应用程序服务器的示例是上文提到的Navic N-Band(TM)服务器。在应用程序数据中心30处创建用于显示VOD内容的模板，并存储到数据库11中，以便由可操作的VOD应用程序使用。例如，可以设计模板使之在标志图框中呈现视频广告内容显示，或在目前被显示的视频内容四周的框中提供导航按钮和观看者选择选项。在下面更详细描述的较佳实施例中，在一系列越来越集中的广告显示类型中使用模板来提供导航帮助。使用视频内容编码器31将原始的视频馈入编码成与VOD平台兼容的格式化的视频内容段，并将它们通过视频内容分配网络14提供给视频服务器12。Referring to FIG. 1A, the overall system architecture for the VOD content delivery system includes a VOD application server 10 located at the cable headend. A VOD application server 10 manages a database 11 of templates and video content segments from a video server 12 for generating templated VOD content. The VOD content is generated in response to a viewer request signal sent from the digital set top box 21 of the viewer's television equipment via the digital cable television system 13 to the VOD application server 10 at the cable headend. The type of the VOD application server 10 may be any compatible VOD application that can be loaded into the server and run on the server. An example of such a VOD application server is the Navic N-Band(TM) server mentioned above. Templates for displaying VOD content are created at the application data center 30 and stored in the database 11 for use by operational VOD applications. For example, a template could be designed to present a display of video ad content in a logo frame, or to provide navigation buttons and viewer selection options in a frame around the currently displayed video content. In the preferred embodiment, described in more detail below, templates are used to provide navigation aids in a series of increasingly focused advertising display types. The original video feed is encoded using a video content encoder 31 into formatted video content segments compatible with the VOD platform and provided to the video server 12 via the video content distribution network 14 .

在运行过程中，VOD应用程序服务器10运行用于CATV系统的VOD应用程序，例如“点播的汽车商业信息片”。通过按下观看者的遥控单元上的键发送一个IR信号到机顶盒21而启用一个用户请求信号，该请求信号经数字电缆电视系统13的底部信道被发送到电缆头端处的VOD应用程序服务器10，观看者便发送了一则选定VOD内容的请求，比如要看特定汽车制造商所制造的特定型号的商业信息片。响应于该信号，VOD应用程序服务器10确定所请求的VOD内容，从模板数据库11中检索商业信息片广告显示模板并从视频服务器12中检索视频内容段，以便生成相应的模板化VOD内容。在本发明中，模板是分级排序的多种不同类型，并且等级更高的模板中的内容显示包括观看者可选的、到层次级别较低的内容的多个链接。当用遥控选择一个链接时，VOD应用程序服务器10检索级别较低的模板和视频内容并将它显示给用户。每一个相继的模板化显示可以进一步包括相继地到层次级别更低的内容的链接，使得观看者可以使用一连串链接的模板化VOD显示作为一种“下查式导航”方法来找到感兴趣的特定目的内容。During operation, the VOD application server 10 runs a VOD application for the CATV system, such as "Car Business Information on Demand". By pressing a key on the viewer's remote control unit an IR signal is sent to the set top box 21 to enable a user request signal which is sent via the bottom channel of the digital cable television system 13 to the VOD application server 10 at the cable headend , the viewer sends a request for selected VOD content, such as a commercial infographic for a particular model made by a particular automaker. In response to this signal, VOD application server 10 determines the requested VOD content, retrieves teaser display templates from template database 11 and video content segments from video server 12 to generate corresponding templated VOD content. In the present invention, templates are of hierarchically ordered different types, and content displays in higher-ranked templates include multiple links selectable by the viewer to lower-level content in the hierarchy. When a link is selected with the remote control, the VOD application server 10 retrieves lower-level templates and video content and displays it to the user. Each successive templated display may further include links to successively lower levels of content, so that viewers can use the chain of linked templated VOD displays as a "drill down" method to find specific content of interest. purpose content.

参照图1B，示出了模板化VOD内容传递系统的较佳实施例，它提供了在显示广告(比如用于汽车商业信息片的显示广告)中使用下查式导航的用户界面。当观看者选择VOD应用程序(频道)时，比如“车轮-点播”，观看者的电视会显示带有各种按钮的主菜单，邀请观看者“选择类别”。观看者可以选择“汽车”类别，然后电视机将显示带有各种按钮的“汽车”菜单，邀请观看者“选择制造商”，比如制造商A、制造商B等。当观看者做出选择时，比如选择制造商A时，观看者的电视机就显示另一个菜单，该菜单是进入模板化VOD内容传递的入口(Gateway)，使模板化的显示广告的下查式导航成为可能。通过该入口，VOD应用程序离开菜单模式并进入下查式导航模式，以便相继地显示分级排序的视频内容，这允许观看者逐步巡航到更密切注意的内容。在本示例中，最高的层次等级包括型号、本地经销商、销售事件和/或存货清单等类别。当观看者从该入口中选择一个类别，比如“型号”，时，该VOD应用程序就创建模板化的广告显示，在框中示出了该汽车制造商的所有型号的视频内容，该框具有到该汽车制造商所制造的特定型号列表的多个链接(按钮或选择)。当观看者选择到特定型号，比如“型号A”，的链接时，VOD应用程序就创建模板化的广告显示，示出了型号A的视频内容，然后观看者可以选择运行型号A的视频商业长信息片。或者，下查式导航可以继续到各种特征级别，比如“定制包装”、“选择”、“颜色/风格”等。相似的是，从入口中选择“本地经销商”类别可以引出用于本地经销商的模板化的广告，其中带有到观看者的电缆服务区域中特定的本地经销商的链接，并且点击特定的“经销商A”可以引出用于经销商A的模板化的广告，其中进一步带有到属于经销商A的更具体的内容(比如“当前的促销”等)的链接。Referring to FIG. 1B, there is shown a preferred embodiment of a templated VOD content delivery system that provides a user interface using drill-down navigation in display advertisements, such as those used for automotive infomercials. When a viewer selects a VOD application (channel), such as "Wheel - On Demand", the viewer's TV displays a main menu with various buttons inviting the viewer to "select a category". A viewer can select the category "Cars" and the TV will then display a "Cars" menu with various buttons inviting the viewer to "select a manufacturer" such as Maker A, Maker B, etc. When the viewer makes a choice, such as selecting manufacturer A, the viewer's TV will display another menu, which is the gateway (Gateway) to enter the delivery of templated VOD content, so that the templated display advertisement can be downloaded navigation is possible. Through this entry, the VOD application leaves the menu mode and enters a drill-down navigation mode to sequentially display the hierarchically ordered video content, which allows the viewer to navigate step by step to the content of closer attention. In this example, the highest hierarchical level includes categories such as models, local dealers, sales events, and/or in-stock lists. When a viewer selects a category from the portal, such as "models," the VOD application creates a templated ad display showing video content for all models of the automaker in a box with Multiple links (buttons or selections) to a list of specific models made by that automaker. When a viewer selects a link to a particular model, such as "Model A," the VOD application creates a templated ad display showing the video content of Model A, and the viewer can then choose to run the video commercial of Model A. info sheet. Alternatively, the drill-down navigation can continue to various feature levels, such as "custom packaging", "selection", "color/style", etc. Similarly, selecting the "Local Dealer" category from the portal can lead to a templated ad for a local dealer with a link to a particular local dealer in the viewer's cable service area, and clicking on a particular "Reseller A" may lead to a templated advertisement for Reseller A, with further links to more specific content pertaining to Reseller A (such as "Current Promotions", etc.).

这样，通过使用作为导航工具的下查式广告，模板化VOD内容传递系统允许用户巡航到非常感兴趣的特定内容，同时具有浏览过一系列广告的独特的可视化经历，这一系列广告反映了用户找到感兴趣的主题的路径。每次用户发出请求时，通过搜索内容/模板数据库，便动态地生成了模板化的VOD广告，从而通过用更新后的链接和视频内容简单地更新数据库，使系统能够显示更新后的导航选择和内容。例如，如果汽车制造商改变目前可购买的汽车的型号，或者如果本地经销商A改变目前可购买的汽车的促销信息，则广告商的广告可以用新的模板框导航链接和内容来更新，而有线电视公司不必再对全新的广告或屏幕显示进行拍摄、制作、签合约、发送和编程。通过使用下查式导航方法，可以启用许多其它类型的多层或纵深的广告、主题和交互式TV应用程序。还可以跟踪、仿形和/或确定通过下查式导航的观看者导航路径所呈现出的各种选择或偏好作为反馈数据，以便广告商细微调节下查式广告的设计。Thus, by using drill-down ads as a navigational tool, the templated VOD content delivery system allows users to navigate to specific content of great interest while having the unique visual experience of viewing a series of ads that reflect the user's Find a path to a topic of interest. Templated VOD ads are dynamically generated by searching the content/template database each time a user makes a request, enabling the system to display updated navigation choices and content. For example, if a car manufacturer changes the models of cars currently available for purchase, or if local dealer A changes promotional information for cars currently available for purchase, the advertiser's ad can be updated with new template box navigation links and content, while Cable companies no longer have to shoot, produce, contract, send and program entirely new commercials or screen displays. Many other types of multi-level or deep advertisements, themes and interactive TV applications can be enabled by using the drill-down navigation method. Various choices or preferences presented through the viewer's navigation path through the drilldown can also be tracked, profiled, and/or determined as feedback data for advertisers to fine-tune the design of the drilldown ad.

在图1C中，一个示例示出了模板化的VOD显示是如何以多层的形式产生的。背景屏幕为显示提供了基本的颜色、标志、或图形主题。在背景上层叠了一个选定的模板(显示框)，该模板适合于原打算的显示所处于的导航等级。该模板通常具有一个框，其中所定义的各区域预留用作文本、显示图像、和导航链接(按钮)。最后，从数据库中检索出由相关的文本、图像和按钮构成的想要的内容，并将该内容层叠到该模板上。所产生的屏幕显示示出了组合后的背景标志或主题、导航框、以及文本、视频图像和按钮。In Figure 1C, an example shows how a templated VOD display can be produced in multiple layers. The background screen provides the basic color, logo, or graphic theme for the display. Overlaid on the background is a selected template (display box) appropriate for the navigation level at which the display was intended. The template typically has a frame in which defined areas are reserved for text, display images, and navigation links (buttons). Finally, the desired content consisting of relevant text, images and buttons is retrieved from the database and layered onto the template. The resulting screen display shows the combined background logo or theme, navigation box, and text, video images, and buttons.

再次参照图1A，可以在电缆头端处安装常规类型的跟踪系统15，以聚集关于观看者观看什么频道和节目等非个人数据。对于下查式导航方法，跟踪系统15可以包括导航路径的跟踪，在VOD应用程序中用户使用这些导航路径找到感兴趣的主题。观看者导航数据的聚集可以指示什么主题是最流行的，在一天的某些时段从人口统计学的角度看或与某些产品或服务相关的情况下某些主题是否更令观看者感兴趣。VOD应用程序服务器10可以将聚集的观看者导航数据输出到外部仿形系统16，比如非偏移的或非相关的稳定应用分布图分析方法。仿形系统16的结果可以被传送到瞄准系统17，比如模板设计公司或内容产生公司，以细调与用户偏好或兴趣一致的模板化VOD内容的呈现过程。来自瞄准系统的反馈可以被提供给VOD应用程序服务器，以修改内容/模板数据库11。Referring again to FIG. 1A , a tracking system 15 of conventional type may be installed at the cable headend to gather non-personal data about what channels and programs a viewer watches. For the drill-down navigation method, the tracking system 15 may include tracking of the navigation paths used by the user to find topics of interest in the VOD application. Aggregation of viewer navigation data can indicate what topics are most popular, whether certain topics are more interesting to viewers at certain times of day demographically or in relation to certain products or services. The VOD application server 10 may output the aggregated viewer navigation data to an external profiling system 16, such as a non-shifted or non-correlated stable application profile analysis method. The results of the profiling system 16 may be communicated to a targeting system 17, such as a template design company or content production company, to fine-tune the presentation of templated VOD content consistent with user preferences or interests. Feedback from the targeting system can be provided to the VOD application server to modify the content/template database 11 .

可以开发用于模板化VOD内容传递系统的另一个应用程序，以便支持按“下查式”方式链接从全国到地方的市场广告活动的视频广告。全国或地方的广告商都可以付费从而使其视频广告放在本系统上。当运行VOD应用程序时，作为入口而显示全国的广告，以链接到地方市场广告。这样，全国的广告可以用于将用户从对某一产品的一般兴趣转移到找到关于该产品在当地可购买的具体信息。Another application for the templated VOD content delivery system can be developed to support video advertising in a "down-look" fashion linking marketing campaigns from national to local. National or local advertisers can pay to have their video ads placed on the system. When running the VOD application, a nationwide advertisement is displayed as an entry to link to a local market advertisement. In this way, national advertising can be used to divert users from a general interest in a product to finding specific information about the product's availability locally.

模板化的VOD内容传递系统也可以支持“通信量构建”视频，其中包括可能不产生直接收入的音乐视频。一旦对视频进行编码并注册到本系统中，则通过软件系统和自动控制来进行视频的管理和分配。该用户界面为用户提供了导航并找到所期望的视频内容的能力。类别的选择为用户呈现出可回放的视频标题的列表。可以用实时数据库询问来产生类别和标题列表，从而允许在该用户界面内对内容进行数据库驱动式管理。该用户界面也可以支持搜索界面，它允许用户搜索视频内容数据库，以产生带有特定特征的视频标题列表。A templated VOD content delivery system can also support "traffic building" videos, including music videos that may not generate direct revenue. Once the video is encoded and registered in the system, the management and distribution of the video is done through the software system and automatic control. The user interface provides the user with the ability to navigate and find desired video content. Selection of a category presents the user with a list of video titles available for playback. Real-time database queries can be used to generate category and title lists, allowing database-driven management of content within the user interface. The user interface may also support a search interface that allows the user to search the video content database to generate a list of video titles with specific characteristics.
